Thanks for all the kind words!
Makes me really happy to know that you played it for such a long time!
The gaming definitely needs a balancing pass for sure!
I don't restart the level when you die, the main reason is that I wanted the game to be instantly playable right after you've upgraded (to hold the player inside the core-loop), all variables are saved in playerprefs, so I could theoretically restart the scene, but because I wanted the game to be completely seamless when "dying" I decided to make all levels out of prefabs instead :). So the reason for the bullets and coins not being removed when dying was just that I did not have time to add a function to remove them when restarting the level.
Definitely agree that the gold should disappear after the bonus round, it will also make the player feel a bit more urgency to collect the gold as fast as possible, good idea! Making the gold appear at the top is also a good idea!
Ooh, that's a nasty bug!
Thought I managed to "kill" all of those, but some managed to escape it appears!
Thanks a lot for playing and for all the feedback!
